GEOL 1003 : GEOL Test 3
Document Summary
Chemical reservoirs: what is a chemical reservoir, =a body of chemical entity that occupies a particular space, e. g. , total volume of h2o on earth or total volume of crust on. Remove players: burial of organic carbon, carbon is not returned to the atmospheric reservoir by respiration processes (recycling) if buried or if not decomposed, marine cycling resembles terrestrial cycling, hypoxic waters, gom dead zone , very little oxygen. Consumed by animals, decayed by decomposers, buried within sed. Mountain building: chemical weathering consumes atmospheric co2, 2. Vegetation: root acids weather rock, effectively negative feedback. Phanerozoic trends: co2 trends during phanerozoic, paleozoic era, devonian. Cause: first ever widespread inland expansion of forests: root acids greatly increased rock weathering, consuming co2, carboniferous. Cause: high burial of organic carbon in coal swamps: burial of organics draws co2 out of the atmosphere. Long term decline in co2 caused global cooling which lead to the carboniferous glaciation of.
